How this service works
Arithmetischer Erwartungswert je Trade. Stichprobenmittel gelieferter Nettoergebnisse, keine Erwartungsprognose. Alle Zahlen, Kurse und Vorgaben liefert der Aufrufer. Keine eigenen Kursdaten, kein Brokerzugriff, keine Ausführung. Rechenwerkzeug, keine Anlageberatung, keine Empfehlung.
Output
Returns the arithmetic sample mean (expectancy) computed from the supplied array of net trade P&L cash values — a single numeric figure representing the average net result per trade. No market data, broker access, or forward-looking forecast is produced.
Example use cases
Backtesting strategy expectancy
“I just ran a backtest and here are my 50 net trade results in USD: [230, -110, 450, -90, 180, -200, 310, 60, -150, 400, -80, 270, -130, 510, -60, 320, -190, 140, -30, 380, -100, 220, -70, 290, -160, 430, -50, 170, -120, 340, -90, 260, -140, 490, -40, 200, -80, 360, -110, 150, -60, 410, -95, 240, -130, 470, -75, 190, -115, 300]. What's my arithmetic expectancy per trade?”
Live trading journal review
“Here are my net cash results for each trade I made this month: [85, -40, 120, -75, 200, -30, 55, -90, 160, -20]. Can you compute the average net profit per trade so I know if my system has a positive expectancy?”
Comparing two trading systems
“I want to compare the average return per trade for my two systems. System A trades gave me these results: [100, -50, 200, -80, 150] and System B gave: [60, -20, 90, -30, 70, -10, 110, -40]. What is the arithmetic mean per trade for each set?”
Technical details
Endpoint
POSThttps://handel.halowerk.com/v1/rechner/expectancy?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, deterministic arithmetic mean of a known list of trade P&L values — especially when you already hold the data locally and want a stateless computation without any broker connection, market data feed, or advisory output. Prefer it over general-purpose statistics libraries when you need a paid, auditable API call for expectancy computation within an automated trading analytics workflow.
Side effects
- Empty array or missing pnl_cash field returns a validation error
- Individual values exceeding ±1,000,000,000,000 are rejected
- Array exceeding 5000 items is rejected
- Non-numeric values in the array cause a type validation error
- Payment failure via x402 prevents request from being processed
